Order Normalization cancels the effect of frequency smearing across spectral bins when the shaft speed is changing rapidly (high slew rate) by resampling triggered by tachometer speed. You can zoom in on an order range with a greatly enhanced resolution Millstrum Analysis (Cepstrum) identifies families of harmonics and sidebands, particularly useful on noisy signals with low-amplitude harmonics or sidebands characteristic of early-stage bearing or gearbox defects Advanced Torsional, torque, windup and belt dynamics and slippage analysis Synchronous Averaging, envelope detection and phase demodulation

eZ-NDT Non-Destructive Test Software Features Provides inspection of metal, ceramic, and hard plastic parts Removes the ambiguity that is common in other inspection systems Requires no parts preparation, making the test fast and inexpensive Tests parts in less than 2 seconds Quantifies and documents the first natural frequency for end user comparison to final assembly resonant frequencies You can use eZ-NDT (non-destructive test) software with a ZonicBook/618E to obtain a fast and inexpensive method of 100% inspection of production parts. Inspection parts include, but are not limited to: powder metal, ceramics, and composites. eZ-NDT uses acoustic analysis to identify part variations that are caused by process inconsistencies and defects. eZ-NDT systems apply acoustic energy to the target part, monitor its acoustic response, and analyze its resonant frequencies. It then compares the results to the acoustic signature of a known-good part stored in its library. The test takes less than two seconds and requires no special tooling, dyes, chemicals, cleaning, magnetization, or expensive and time consuming visual inspection equipment. eZ-NDT can detect deviations in dimensions, material properties, and defects including cracks, residual stress, inclusions, and variations in hardness, tempering, porosity, mass, holes, bonding and/or welding failures. Resonant inspection performs a whole body measurement, not just a spot check for visual indications. It also quantifies the first natural frequency, which many end users require for comparison to final assembly resonant frequencies. By keeping component first natural frequencies different from final assembly resonant frequencies, the end user avoids the potential for noise, vibration, or product damage. And because it’s fast, you can test all of your parts, not just a cross sampling. Before purchasing an eZ-NDT system, we recommend that you engage in our Feasibility Study. This study, discussed briefly in upcoming text, verifies that the intended inspection pieces will respond appropriately to the eZ-NDT inspection process.
